Implementations

impl ObjectId

Access and conversion

pub fn kind(&self) -> Kind

Returns the kind of hash used in this Id

pub fn as_slice(&self) -> &[u8]

Return the raw byte slice representing this hash

pub fn as_mut_slice(&mut self) -> &mut [u8]

Return the raw mutable byte slice representing this hash

pub const fn empty_tree(hash: Kind) -> ObjectId

The hash of an empty tree

Returns true if this hash consists of all null bytes

pub const fn null(kind: Kind) -> ObjectId

Returns an Digest representing a hash with whose memory is zeroed.

impl ObjectId

This impl block contains no items.

Sha1 hash specific methods

impl ObjectId

Hash decoding

pub fn from_hex(buffer: &[u8]) -> Result<ObjectId, Error>

Create an instance from a buffer of 40 bytes encoded with hexadecimal notation.

Such a buffer can be obtained using oid::write_hex_to(buffer)

Methods from Deref<Target = oid>

pub fn kind(&self) -> Kind

The kind of hash used for this Digest

pub fn first_byte(&self) -> u8

The first byte of the hash, commonly used to partition a set of Ids

pub fn as_bytes(&self) -> &[u8]

Interpret this object id as raw byte slice.

pub fn to_hex_with_len(&self, len: usize) -> HexDisplay<'_>

Return a type which can display itself in hexadecimal form with the len amount of characters.

pub fn to_hex(&self) -> HexDisplay<'_>

Return a type which displays this oid as hex in full.

pub fn hex_to_buf(&self, buf: &mut [u8]) -> usize

Write ourselves to the out in hexadecimal notation, returning the amount of written bytes.

Panics if the buffer isn’t big enough to hold twice as many bytes as the current binary size.

pub fn write_hex_to(&self, out: impl Write) -> Result<(), Error>

Write ourselves to out in hexadecimal notation
